ABSTRACT:
A slide mount includes a readily removable strip of bosses for engaging the perforations at one edge of the film which can be fitted in at least two different positions in one or more grooves, including at least one position where the distance between the longitudinal centerline of the window to the centerline of the bosses on the boss strip differs by a predetermined displacement from the nominal distance from the perforations on the film to the longitudinal centerline of the film. Each window is preferably provided with two grooves, one above and one below the window opening; the centerline of the bosses is preferably offset from the centerline of the boss strip by a fixed amount. By selectively placing the single boss strip in either of two orientations in either of the two grooves, the vertical position of the film may be displaced by different amounts. In a stereo version of the mount having two windows, one for each film image, each window has its own associated boss strip and the vertical position of each of the two individual film images is thereby individually positionable with respect to its window.
